Jockey James Doyle had not ridden a winner at Royal Ascot until Wednesday but the 25-year-old Englishman made up for it in style with a superb treble in front of an admiring Queen Elizabeth.

Inspired by a textbook ride to win the Group One Prince Of Wales's Stakes aboard Al Kazeem, Doyle coaxed a recalcitrant Belgian Bill to victory in the Royal Hunt Cup before setting Rizeena alight in the Queen Mary Stakes.

Not since Frankie Dettori landed his magnificent seven in 1996 has the royal racecourse bowed to the talents of a youthful sorcerer.

"It is what you aspire to when you are growing up, so it makes me very happy to be standing here after a day like today," Doyle said.

Al Kazeem gave Doyle his first European Group 1 winner when he mastered last year's double Derby winner Camelot in Ireland last month. The latter's connections were optimistic their horse might turn the tables but Al Kazeem extended his superiority as Camelot laboured home in fourth place.

It was a disappointing effort from a horse who came close to winning the coveted British Triple Crown last season.

Al Kazeem, for his part, is now the best older horse in Britain, with only Cirrus des Aigles - who reappears at Saint-Cloud on Sunday - rated superior in Europe.

The five-year-old Al Kazeem fractured his pelvis when making a winning seasonal debut last term but has returned to the fray with purpose.
